After the Tang Dynasty, it can be divided into ancient poetry (ancient style) and modern poetry (modern poetry, metrical poetry).
Antique can be divided into: general antique (including five-character ancient poems and seven-character ancient poems) and antique quatrains.
Modern poetry includes: regular poems (five-character regular poems, seven-character regular poems and "long-character regular poems") and quatrains (five-character quatrains and seven-character quatrains).
That's it in a nutshell. Please refer to the reference book for details.
